BAG-HOLDER.

Specication of Letters Patent.

lsatented June 2, 1908.

Application filed January 28, 1907. Serial No. 354,580.

To all whom 'it may concern.'

Be it known that I, CHARLEs L. BOND, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles .and State of California, have invented a new and useful Bag-Holder, of which the following is a specification;

j It is one of the objects of this invention to provide a device for holding bags in connection with automatic weighing scales, and to provide means whereby the bag may be readily and rapidly adjusted in place without inconvenience in the successive iilling and wei hing of large packages from material in bu k; to provide a simple, compact device which is readily adapted to be used in connection not only with scales, but in connection with other means, and to produce an inexpensive yet substantial structure.

Another object is to provide for perfect ad justability of the bag-holder to bags of various sizes and thickness, and to avoid liability of tearing or otherwise injuring material of which the bag is made.

Further objects are convenience of assembling and taking apart, and compactness for storage and transportation.

The device is applicable for suspending by their mouths, sugar bags and other bags that are required to support heavy weights as 100 pounds of material, more or less, while being filled and weighed, said bags being frequently of great thickness or of more than one thickness, as of coarse material as jute for an outer cover, and cheese-cloth or the like for inside lining, it being necessary to hold both outer and inner bags without allowing the same to slip or tear when the weight comes on them.

A further object is to hold bags of different sized mouths without changing the adjustment of the holder also to hold the bags l without stretching or straining them; and to support the bag at four places, thus to hold the mouth widely open beneath a hopper as the same might be held by the hands of two attendants though with perfect steadiness.

In the drawings, Figure 1 is a side elevation of a bag-holder embodying the invention. The releasing position of the operating lever and means for holding the bag are shown in dotted lines. Fig. 2 is a plan view, the hopper being shown partly broken to illustrate the operating mechanism which is shown in holding position. Fig. 3 is a rear elevation of the device in releasing position. Fig. 4 is a fragmental elevation of one pair of the lugged and apertured jaws viewed from the left of Fig. 1, omitting the bag. Fig. 5

is a fragmental section of the same jaws viewed from'line x5, Fig. 3, holding a two-ply bag.-

1 is an upright support mounted on a suitable base t and having fixed thereto and extending away at right angles to said support 7 designates jaw members adjustably iixed ,n

to the frame 2 by clips 7 and set-screws .7l and provided with openings 8.

9 designates depending jaw members having lugs 10 arranged to enter the openings 8 of the members 7 to clamp one side of the bag. The depending jaw members 9 are adjustably seated on the carrier 5 and are secured by set-screws 11.

The interlocking jaw members dare arranged 1n palrs 1n a common horizontal plane, so as to interlock to clamp a bag when moved relatively in right lines horizontally and longitudinally of said members.

12 designates aw members each provided with a lug 13, said jaw members being adjustably mounted on the frame 2 and secured by clips 12 and set-screws 12.

14 designates depending members adjustably mounted on the carrier 5 and secured by set-screws 15 extending through the top thereof and bearing against the carrier. The members 14 are provided with oriices 14 to receive the lugs 13.

1.6 is a block adjustably secured midway of one of the carrier-rods 5 and having pivotally attached thereto a link or connectingrod 17 which is connected to a crank-arm 18 by means of pin 19, the inner end of which terminates in a U-shaped hook 20 which extends underneath one of the carrier-rods 5 and engages the same when the link 17 is just above dead center with the crank-arm 18, thus to limit the movement of the link r said shaft 21 is bent to form a lever and is provided with a handle 22 which serves to l in Figs. 1 and 2, the carrier 5, 6, and its jaws 9 and 14 will be moved forward to cause the lugs 10 and 13 to project into the openings 8 and 14. At this osition of the handlethe hook 20 engages the carrier-rod 5 above it, thus stopping the handle in position from which it will not return by gravity on account of the up-bent position of oint 19. The joint at 19 thus acts as a toggle-joint to hold the jaws closed a ainst. the pressure exerted thereon by the ag while being filled. Whenever the handle is depressed, the carrier moves rearwardly, thereby opening the bagholder to allow the bag 23 to be removed or placed as the case may be.

Preferably, the rear lugs 13 are' stationary,

,. as shown, and project rearwardly, so that the operator may hook the rear side of the mouth of the bag thereon and secure it by drawing forward on the bag. He may then bring the front side of such mouth forward and hook the same over the forwardlyrojecting movable lugs 10. Then by pu ing the mouth of the bag sidewise with the left hand, such mouth will be retained firmly by the lugs, thus allowing the operator to use his right hand to bring the handle to horizontal position, thereby moving the members 14 forward to encircle the portions of the bag caught by lugs 13, and at the same time moving the lugs 10 forward to bring into the holes 8 the portions of the bag caught on the lugs 10. The bag will thereby be' held until the handle is returned from its horizontal position, whereupon it becomes releasable.

The adjustable members 7, 9, 12 and 14 may be moved to any position relative to each other, thus to adapt the holder to secure bags of various widths of mouth and thickness of material. The stop formed by the hook 2O is designed to prevent the jaws from coming so close together as to cut or injure the bag.

The blocks 16 are adjustably fixed on the carrier-arms or rods 5 by means of setscrews 16l the inner ends of which engage the rods, and the outer portions ofwhich form the wrist-pins for the links 17 The horizontal frame or support 2 extends forwardly from the hopper so as to afford a considerable adjustment of the jaw members 7.

By reason of the set-screws the appliance can be readily adjusted throughout a wide range, and the parts can be easily assembled and disassembled.

The supporting frame indicated in a general way by the character 2 maybe composed of three U-shaped parts; viz.,-a bracket 23 fastened to the channel-iron up,- right support 1 byl bolt 24, and two`side arms 25 riveted thereto by rivets 26.

The hopper 3 may be detachably secured to the arms 25 by stove bolts 27.

By simply bringing the handle 22 to horizontal position and removing the stove-bolt 24, the frame and carrier can be lowered to the base b or removed from the support post 1 for convenience of storage or trans ortation. Or, if desired to make the evice more compact, the set-screws and stove bolts may be loosened and all the parts except those of the frame, be disassembled.

By reference to Figs. 4 and 5 it will be seen that the lugs 13 are of considerably less diameter than the openings 14 and that the bag-engaging end of the lug 13 is rounded to simply tuck the material of the bag into the opening. The lug may be formed of a taperstud driven into a taper-hole, as 13, so that in case the lug becomes worn it may be driven out and replaced with new.

The base b may be the platform of weighing scales so that when the bag is suspended from the holder and free from other support the weight of its contents', as the bag is being filled, will be supported by the scales, and will stretch the bag into smooth form.
